This invention relates to sponge brushes.

An object of this invention is to incorporate sponge sections, or wholesponges, into an implement provided with a handle in order that they maybe formed into convenient shapes and conveniently used.

Another object of this invention is to incorporate sections of sponges,or whole sponges, into an implement of the character described by meansof a twisted wire and to provide means to prevent the wire when twistedfrom shearing the sponge material.

Other objects will be apparent from the following detail descriptiontaken in connec tion with the accompanying drawing, in which Fig. 1 is aplan view of the brush.

Fig. 2 is a longitudinal cross section.

Fig. 3 is a section through the tip.

Fig. 4 is a cross section.

Fig. 5 is a cross section similar to Fig. 4 but taken on a differentplane.

A Wire 1 is folded over itself and twisted in order to secure the spongematerial between its folds. Sponges or sponge sections 2 are insertedand held between the folds and preferably these sections are ofdecreasing size from the tip to the handle, as clearly shown in thedrawing, Figs. 1 and 2.. The free ends 3 of the wire are inserted andheld in a handle at, as best shown in Fig. 2.

We have found in actual practice that unless some means are provided toprevent the wire from shearing the sponge material, the brush when usedon rough work is of comparatively short l fe. In order to overcome thisdifficulty strips of chamois 5 are inserted between the folds of thewire where the wires cross, thus leaving a considerable space betweenthe folds of the wire for the sponge sections 2 and preventing the foldsof the wire from shearing the sponge material.

The tip end of the brush is protected by a piece of chamois 6 twistedaround the tip loop 7, as best shown in Fig. 3, thus preventing the barewire from striking and scarring the material upon which the implement isused.

It will thus be seen that an instrument has beenprovided which may beeconomically manufactured, and which has incorporated 1931. Serial No.538,706.

in it sections of sponges, and that means have been provided which addto rather than des tract from the usefulness of the brush and whicheffectually prevent the wires used in the construction of the brush fromshearing the sponge material.

It will be obvious that parts of the invention may be used without thewhole, and that various changes may be made in the details ofconstruction, within the scope of the appended claims, without departingfrom the spirit of this invention.

We claim:

1. An implement of the character described including a wire folded andtwisted, a plurality of sponge sections secured between the folds of thewire, strips of tough non-metallic material interposed in the folds atthe points where the wire crosses itself, and a handle secured to thefree ends of the folded wire.

2. An implement of the character described including a wire folded andtwisted, a plurality of sponge sections secured between the folds of thewire, strips of chamois secured between the folds of the Wire at pointswhere the wire crosses itself, and a handle secured to the free ends ofthe wire.

3. An implement of the character described including a wire folded andtwisted, a plurality of sponge sections secured between the folds of thewire, strips of chamois secured between folds of the wire at pointswhere the wire crosses itself, a strip of chamois twisted about the tipfold of the wire, and a handle secured to the free ends of the wires.
